STATIC, BALLISTIC and DYNAMIC STRETCHING Flexibility, one of the health-related components of fitness, can be improved by incorporating stretching into one’s physical fitness program. The three modes of stretching used to increase flexibility include ballistic, static stretching, and dynamic. Ballistic Stretching exercises are performed using rapid, bouncy movements which provide force to lengthen muscles. Although this particular type of stretching has been indicated to improve flexibility, it also can lead to injury due to tearing of muscle tissue. Similarly, ligaments (which connect one bone to another) can be overstretched, which can promote joint instability. Loose joints may further lead to subluxation and dislocation. Static Stretching involves the slow, gradual lengthening of a muscle. Once a final position is reached, the stretch is held for several seconds. Because the stretch occurs slowly, the muscle can relax, resulting in greater length. This is the stretching technique practiced most frequently among fitness professionals, and poses very low injury risk. Dynamic Stretching involves movement while stretching a muscle or muscle group, without the bouncing associated with ballistic stretching. To optimize performance and minimize injury risk, all stretching should be performed when the body’s muscles are warm.
